Rogue RDP Connections
Since I noticed my ethernet connection performance as being saturated on my Windows 2012 R2 server, I ran the netstat command & noticed alot of ip addresses having established connections to 3389. When looking further, I see that these ip addresses are from many different countries like korea, china, russia, turkey... What can I do to prevent these rogue connections? Are they authenticating to my server? Could there be an app on the server thats allowing this?
